Emergency Lighting Failed Monthly or Annual Test
An emergency light or exit sign did not stay on long enough during the test. The internal battery needs to be replaced, or the unit itself needs to be swapped out.

Professional
Technical view
Emergency luminaire failed the NFPA 101 7.9.3 monthly 30-second test or the annual 90-minute full-duration test. Root cause is typically battery degradation, driver board failure, or LED head failure.
What inspectors find
An emergency light or illuminated exit sign that will not turn on when the inspector presses the test button, or that turns on but shuts off before the 90-minute minimum duration required for annual testing.
Why it matters
Emergency lighting exists to illuminate the egress path during a power failure. If the lights do not work, occupants cannot see to evacuate — which is the exact scenario the code exists for. A fire that trips the building power is also the scenario when people most urgently need emergency lighting. A failed unit means a section of the egress path is dark during an actual emergency.
Common causes
- Internal lead-acid or NiCad battery reached end of service life (typical 4-7 years)
- LED driver board failed (common in older combination unit designs)
- Lamp heads or bulbs burned out (older incandescent models)
- Unit never recharged properly because the AC supply was intermittent
- Water damage, vandalism, or physical impact to the unit
How it gets corrected
For battery-only failures, the internal battery is replaced and the unit is re-tested for 90 minutes to confirm the new battery holds. For driver or lamp failures, the entire unit is usually replaced — new LED combination emergency light + exit sign units are inexpensive and more energy-efficient than repairing older designs. Replacement units should be installed by a licensed electrician and documented in the ITM record.
For buildings with 50+ emergency fixtures, a batch replacement approach usually beats one-at-a-time repair: inventory all units, identify the ones at 5+ years of age, and plan a rolling replacement over a 12-month window. This eliminates ongoing failures and smooths the budget.

Timeline guidance
Typical AHJ correction timeline
Failed emergency lighting is typically a 30-day correction. The specific unit may need to be taken out of service or bypassed during the correction, which does not create a code compliance gap as long as other units cover the same area.
Common questions
What is the 30-second monthly test versus the 90-minute annual test?＋
Every month, a brief 30-second test confirms the unit comes on when AC power is removed. Once a year, a full 90-minute test confirms the battery can sustain the full required duration — this catches units that start fine but shut off early. Both tests are required under NFPA 101.
Can I do the monthly test myself?＋
Yes. Monthly testing is typically done by in-house facilities staff — press the test button on each unit, confirm the lamps come on and stay on for 30 seconds, log the result. The annual 90-minute test requires timed documentation and is usually part of your annual inspection contract.
If one unit fails, do all units need to be tested?＋
Just the failed unit requires correction, but a widespread failure (multiple units in one wing) usually indicates a shared root cause — a common battery supplier batch, an inconsistent AC branch circuit, or an environmental issue (heat, moisture). An inspection of adjacent units is usually warranted.
How much does emergency light replacement cost?＋
A modern LED combination emergency light + exit sign unit runs $40 to $150 in parts. Labor is typically 20-30 minutes per unit for direct replacement. A commercial facility replacing 25 old units typically budgets $2,000 to $4,500 all-in.
